1072 6680 d 13 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.

1066 6680 d 23 h jermar /kernel/trunk/ Support for user space threads.  
1063 6681 d 1 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6681 d 2 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
1060 6681 d 3 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.		  
1050 6681 d 8 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.		  
1048 6681 d 10 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1044 6681 d 11 h jermar /kernel/trunk/ Page table locking.  
1040 6681 d 12 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.		  
1037 6681 d 13 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1032 6682 d 0 h jermar /kernel/trunk/generic/ mmap() syscall.  
1027 6682 d 0 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1026 6682 d 1 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1005 6682 d 13 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
1002 6683 d 0 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
998 6683 d 1 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
980 6683 d 10 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6683 d 10 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6683 d 12 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6683 d 15 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
959 6684 d 4 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6684 d 4 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
955 6684 d 5 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6684 d 8 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
946 6685 d 2 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
940 6685 d 5 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6685 d 6 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6685 d 7 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
910 6692 d 11 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6692 d 13 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
906 6695 d 0 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
897 6698 d 0 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
